Have been playing some MP with randoms over the past few days, and as usual, the problem is everyone is far too good for me!

Will have to try and find a time of day with similarly bad players to me I think, or more likely stick to Horde / Beast in future...

Still haven't touched the main campaign. Does anyone have any thoughts on Raam's Shadow? Are there any spoilers if I play it now before starting the main campaign? What's the difference between 'standard' and 'arcade' modes?
